1. A sensing device, comprising:
a first layer;
a second layer;
a sensor device platform comprising a plurality of stretchable optical fibers disposed between the first layer and the second layer, wherein the plurality of stretchable optical fibers comprise one or more elastomer materials;
one or more light sources, each of the stretchable optical fibers being connected to at least one of the light sources;
one or more light detectors each connected to at least one of the stretchable optical fibers and each configured to receive light signals emitted from the one or more light sources and transmitted by the stretchable optical fibers;
a control unit that receives inputs associated with the received light signals from the one or more light detectors and that determines one or more deformation states of the second layer based on the received input;
a printed circuit board, wherein the one or more light sources, the one or more light detectors, and the control unit are affixed to the printed circuit board; and
a power source affixed to the printed circuit board such that the power source is coupled to the control unit.
